I'm A Teen Who Built A 'Can Cooler' Business — It Brings In $808,000/Year
19-year-old Mike Satterlee built CruiseCup, a double-can cooler business that generated $808,000 in revenue in 2025 by leveraging 3D printing and later transitioning to stainless steel manufacturing. He forgoed college to grow the business full-time, using AI automation to operate lean with minimal overhead while working 80-85 hours per week.
Summary
Mike Satterlee is a 19-year-old entrepreneur who built CruiseCup, an innovative double-can cooler business that achieved $808,000 in gross revenue in 2025. He has been entrepreneurial since childhood, starting his first business at age 13 selling sand repellent lotion, which taught him e-commerce fundamentals. He continued with 3D printing product design in high school before launching CruiseCup in May 2025, just before graduation. The core innovation is a double-can cooler that opens at both top and bottom, allowing access to the second can.
Mike made a deliberate decision to skip college, committing to a one-year test of the business with a fallback plan to attend if it failed. The business immediately found product-market fit after a viral social media post. His operation includes a warehouse with over 160 3D printers running 24/7, initially producing the entire product line. He employs one full-time employee for fulfillment and handles all business operations, accounting, social media, and customer support himself, working 80-85 hours weekly.
The business operates with significant automation, incorporating AI for print farm management, email workflows, and customer support to minimize overhead. Between January and September 2026, revenue reached $601,000. A critical scaling decision came in July 2026 when he transitioned from 3D printed coolers to stainless steel manufacturing, a transition in development since October 2025. He filed two utility patents for the double-can cooler design to protect against copycats.
Key financial insights show gross revenue of $808,000 in 2025 with $117,000 spent on 3D printers and filament. He operates profitably, reinvesting all profits into product development and inventory rather than taking a formal salary, living with his parents to minimize personal expenses. The stainless steel transition proved necessary for scalability; during the previous Christmas season, demand became so overwhelming he had to remove listings to avoid unfulfilled orders, resulting in significant opportunity loss.
Future plans include B2B sales with custom logos for trade shows, expanding into traditional drinkware products by late 2027/early 2028, and ultimately securing placement in major box retailers. He has ruled out college entirely, committing fully to scaling CruiseCup into what he envisions it can become.
Key Insights
- Mike identified a problem with standard single-can coolers (inability to access a second can) and solved it by designing a cooler open at both top and bottom, enabling the core product innovation that drove market success.
- The business achieved immediate traction after a viral social media video, indicating rapid product-market fit validation that gave him confidence to commit full-time to CruiseCup.
- Mike uses AI automation for print farm management (keeping printers running 24/7 autonomously), email workflows, and customer support to operate with just one full-time employee and minimize overhead costs.
- The transition from 3D printing to stainless steel manufacturing (July 2026) became necessary because 3D printing couldn't scale sufficiently—adding more printers required prohibitive space and long-term costs exceeded overseas manufacturing, despite the 180-day production cycle disadvantage.
- During the previous Christmas season, demand exceeded fulfillment capacity to the point where Mike had to stop accepting orders and remove listings midway through December, resulting in losing approximately half the month's potential revenue due to not having transitioned to stainless steel sooner.

[0:02] I wanted to innovate a standard can cooler. The first thing I thought is what good is just one can. So I made it hold two cans and then if a can cooler holds two cans, you're not going to be able to drink the bottom one. So I made it open at both the top and the bottom, so you can easily get to the second can by placing the first one in the bottom. My name is Mike Satterlee and I'm 19 years old. My can cooler business, CruiseCup brought in about $808,000 in 2025. So I've been an entrepreneur my whole life. Ever since I was a kid [0:33] I've been always doing everything I could…
